In Japanese mythology, Ichimokuren is the one-eyed god of wind and storms as well as the god of smithery. He is often invoked by farmers during droughts to bring rain, or worshipped by blacksmiths to keep good skill and business. When angered, Ichimokuren's powerful winds can cause fearsome tornadoes, blowing the roofs off houses and knocking over ships at sea.
"A spirit known as the god of wind, as well as the god of smithery. His strong winds blow roofs and people away, and knock over ships in the sea."
—Devil Summoner: Raidou Kuzunoha vs. The Soulless Army devil chart
Ichimokuren is the fifth demon of the Wind Order and can only be recruited through fusion. Ichimokuren is summoned by Rasputin to stop Raidou Kuzunoha the XIV from leaving the Daidouji Residence in pursuit of Kiyoshi Daidouji after witnessing him transforming into the Red Cape. This is the last boss of the first episode of the game. Ichimokuren will guard by closing his eye, which makes him impervious to damage, he will remain this way until two Turdaks acting as his support are defeated. This will continue until he becomes low on health, at which point he will summon Turdak as support while remaining on the offensive. Raiju or another demon of the Volt Order will easily exploit his weakness when his eye is open to deal damage.
After being defeated, Raidou can summon Ichimokuren in the Gouma-Den once he reaches level 38.
